JAMES A.BECKWITH <br /> FONTANARI OBJECTIONS AND COMMENTS I SNOWCAP BOND APPLICATION SL-1 1 I PG.6 <br /> of Tract No. 70, Mr. Magers found and photographed surface subsidence cracks. In 1985, <br /> (Figs. 10 and 11), there were six parallel tension cracks on the surface varying in depth from <br /> 1/2 to 1 ft. and from 1-2 ft. in width. (M. at 11.) In 1991, there was but one tension crack <br /> varying from 1-2 feet in width; from 1-9 feet in depth; and stretching 200 feet across the same <br /> route as the six cracks noted in 1985. (M. at Fig. 12.) <br /> The Magers Report does not provide specific coordinates for any of the tension cracks he <br /> observed in 1985 and 1991. Mr. Magers, in his Figure 10, only identified that the cracks ran <br /> generally east-west between Rods A5 and A-6 on the west through Rods B-6 and B-7 on the <br /> east. Using current technology, two overlays were created of, first, Mr. Magers' Figure 10 <br /> with an aerial photograph of the Study Area and, second, Mr. Magers' Fig. 10 with the 1980 <br /> GEX Mine Map. (Fontanari Exhibit 7) On August 24, 2018, Rods A-5, A-6, B-6 and B-7 <br /> were located in the field. This revealed that Mr. Magers' 1991 crack is now a line of deep <br /> sinkholes in the same location including one such sinkhole that is measured to be at least 24 <br /> feet deep. <br /> On or about February 28, 1992, Powderhorn Coal Company created a map of the <br /> Northwest Section in anticipation of a request to modify its application before DBMS. (see <br /> Exhibit 2) On this map, Powderhorn identified those tunnels under the plateau of Tract No. <br /> 70 in which there had been roof collapses which left the tunnels inaccessible. This 1992 map <br /> revealed a length north-south line of collapsed tunnels running underneath the eastern <br /> boundary of Tract No. 70, and below a present line of sinkholes on the western edge of the <br /> canyon in Tract No. 70. <br /> In December 2015, DBMS and Snowcap entered into MR-82. There, Snowcap agreed to <br /> investigate all lands owned by Fontanari for the purpose of repairing, if needed, hydrologic <br /> communications between surface water and underground mine tunnels. Snowcap proposed a <br /> repair for only one sinkhole on Tract No. 71 and did not investigate or make any report to <br /> DBMS concerning any other Fontanari lands. <br /> In April 2016, a Fontanari research team conducted a site inspection of Tracts Nos. 70 <br /> and 71 using the same procedure DRMS employed in its August 2018 inspection. They <br /> walked the entirety of Tracts Nos. 70 and 71 to find and GPS man-made items (e.g., <br /> subsidence rods and SCP's) as well as natural items such as sinkholes, depressions, or surface <br /> tension cracks. In Tract No. 70, SCP 201 was found and noted on the 2016 Survey Plat <br /> created by Walter Eldridge, PLS 11980. (Fontanari Exhibit 8.) The A, B, and D Lines of <br /> subsidence rods Mr. Magers set were also found and platted on the 2016 Survey Plat. (Id.) <br /> By 2016, however, tension cracks were not observed on the surface. Instead, a series of <br /> "inline sinkholes" were found in the same location as the 200 feet long, 9 feet deep stress <br /> crack Mr. Magers noted in his Figure 10. (Id.) In Tract No. 70, two surface subsidence <br /> depressions and numerous sinkholes were logged. In October 2016, an additional inspection <br /> revealed more sinkholes, which were again photographed and platted on another Eldridge <br /> Survey. (Fontanari Exhibit 9.) <br />
